The bridge mechanism 110 includes a bridge main body 111 disposed on the surface of the upper shell 102 and a string support member disposed in the string support member accommodating portion 112 of the bridge main body 111 for holding each guitar string 100. (Saddle member) 115
And one end of each guitar string 100 supported by the string support member 115 is integrally fixed to the string stopper hole 114 of the bridge body 111 by a plurality of fixing pins 120. Reference numeral 103 shown in the figure represents a bridge plate (bridge pad) for reinforcing the upper plate 102. The illustrated bridge mechanism 110 is used for a flat-top guitar in which the distance between a guitar string and a guitar body is relatively narrow among acoustic guitars. A bridge mechanism (double-girder bridge mechanism) equipped with a vertical adjustment mechanism that can be adjusted for the height of the strings is used for arch top guitars, etc., which are fixed by the method but the distance between the guitar strings and the guitar body is relatively wide. There are many.

In recent years, as shown in the figure, a pressure-sensitive pickup (also called a piezo pickup) 125 composed of a pressure-sensitive element is incorporated below the string support member 115 of the bridge mechanism 110, and the string support member 115 is interposed therebetween. The pressure-sensitive pickup 125 is compressed and expanded by the transmitted string vibration of the guitar string 100, thereby generating an electric signal and extracting the pickup output (electric sound). Instead of taking out the pickup output by the pressure-sensitive pickup 125, an electromagnetic pickup device (magnetic pickup device) having a coil and a magnet and generating an electromotive force by virtue of an electromagnetic induction action with the vibration of the guitar string is incorporated in the guitar body. Sometimes the pickup output is taken out.

In the case of using the pressure-sensitive pickup 125, since the string vibration is physically picked up, the output sound has a sharp rise, the attenuation is smooth, and the sound of a non-magnetic nylon string or the like is also generated. Can be picked up,
Further, since no coil is used unlike the electromagnetic pickup device, no induction noise is picked up.

1 Except for the part protruding from the surface. ) Is the bridge body 11
It is in direct contact with the inner wall surface 113 of the first string support member accommodating portion 112. Therefore, most of the string vibration from the guitar strings 100 leaks from the string supporting member side surface 116 to the bridge main body 111 near the guitar strings 100, more specifically, at a position immediately below each of the guitar strings 100, and Only a part of the vibration is transmitted to the pressure-sensitive pickup, and there is a problem that the efficiency of propagating the string vibration to the pressure-sensitive pickup 125 is poor.

As means for solving the above problem, as shown in FIG. 21, the distance between the inner wall surfaces 133 of the string support member accommodating portion 132 of the bridge body 131 is determined by changing the distance between the string support members 13.
5 is filled with resin M between the string supporting member 135 and the pressure-sensitive pickup 145 and the string supporting member accommodating portion 132, so that the side surface 136 of the string supporting member 135 and the bridge main body are filled. It is conceivable that a gap 150 is provided between the inner wall surfaces 133 of the string support member housing portion 131 of FIG. However, according to this means, not only the strength of attachment (stability) of the string support member 135 to the bridge body 131 is insufficient, but also the resin M deteriorates with time and the string of the resin
The resin M is crushed due to insufficient strength against the force acting in the tension direction X of the string via the string support member 35 and the string support member 13
5 is inclined in the string tension direction X and the side surface 1 of the string support member 135
There is a possibility that the string vibration may leak to the bridge main body 131 at the contact portion between the 36 and the inner wall surface 133 of the string support member accommodating portion 132. In FIG. 21, reference numeral 102 denotes a top of the guitar body, 103 denotes a bridge plate (bridge pad) for reinforcing the top 102, 130 denotes a bridge mechanism, 134 denotes a string stopper hole formed in a bridge main body 131, and 140 denotes a string stopper hole.
